<P CLASS=para>
The <tt CLASS=literal>PropertyEditorManager</tt> class is never meant to be
instantiated; it defines static methods for registering and
looking up <tt CLASS=literal>PropertyEditor</tt> classes for a specified
property type.  

<P CLASS=para>
A Java bean may specify a particular <tt CLASS=literal>PropertyEditor</tt>
class for a given property by specifying it in a
<tt CLASS=literal>PropertyDescriptor</tt> object for the property.  If it
does not do this, the <tt CLASS=literal>PropertyEditorManager</tt>
is used to register and look up editors.  A bean or an
application builder tool may call the
<tt CLASS=literal>registerEditor()</tt> method to register a
<tt CLASS=literal>PropertyEditor</tt> for properties of a specified type.
Application builders and bean <tt CLASS=literal>Customizer</tt> classes may
call the <tt CLASS=literal>findEditor()</tt> method to obtain a
<tt CLASS=literal>PropertyEditor</tt> for a given property type.

<P CLASS=para>
If no editor has been registered for a given type, the
<tt CLASS=literal>PropertyEditorManager</tt> attempts to locate one.
For a type <I CLASS=emphasis><tt CLASS=literal>x</tt></I>, it looks for a class
<I CLASS=emphasis><tt CLASS=literal>x</tt></I><tt CLASS=literal>Editor</tt> first in the same package as
<I CLASS=emphasis><tt CLASS=literal>x</tt></I>, and then in each package listed in the
property editor search path.
